Our CO₂ (R744) unit cooler / transcritical evaporator is purpose‑built for supermarket booster refrigeration systems, supporting both transcritical and subcritical R744 operation. As natural‑refrigerant hardware with GWP=1, it helps retail operators comply with EU F‑gas regulations and phase‑down schedules for synthetic refrigerants.
We supply custom‑engineered supermarket CO₂ unit coolers covering medium‑temperature and low‑temperature duties, cooling capacity from 5 kW up to 80 kW. Reinforced high‑pressure coil construction with thick‑wall tubes and heavy‑duty headers meets supermarket transcritical system design pressure requirements up to 100 bar, every unit undergoes strict pressure‑holding and leak‑testing before delivery.
Multiple coil material options are available: high‑pressure carbon‑steel tubes, 304 / 316L stainless‑steel coils for hygienic food‑retail environments, paired with hydrophilic epoxy‑coated aluminium fins to reduce frost accumulation and keep stable heat‑transfer performance under frequent defrost cycles.
Fan packages can be configured with energy‑saving EC variable‑speed fans or AC axial fans, IP54 / IP55 motor protection for supermarket back‑room cold‑room conditions. Electric defrost or hot‑gas defrost can be selected according to MT / LT operating mode. Unit housing options include galvanized steel or full 304 stainless steel for food‑safe hygiene requirements.
Typical supermarket retail applications: walk‑in chillers, walk‑in freezers, back‑store cold rooms for fruit & vegetable, dairy, meat and frozen‑food storage for hypermarkets, discount stores and neighborhood supermarkets.
Send us your required cooling capacity, MT/LT operating mode, system design pressure, site voltage and room dimension, our engineering team will deliver a tailor‑made CO₂ unit cooler solution for your supermarket project.
